onsemi's Strategic Acquisition of Vcore Power Technologies: A Catalyst for Dominance in the AI-Driven Power IC Market

The semiconductor industry is witnessing a seismic shift as artificial intelligence (AI) redefines the power infrastructure of data centers. At the forefront of this transformation is onsemi, which has announced its acquisition of Aura Semiconductor's Vcore Power Technologies to bolster its position in the high-growth power IC market. This move, set to close in Q4 2025, underscores onsemi's commitment to addressing the escalating energy demands of AI infrastructure while differentiating itself in a competitive landscape marked by rapid innovation and capital-intensive investments.

Market Dynamics: Power ICs as the New Bottleneck for AI Scalability

The global power IC market for AI/data centers is surging, driven by the exponential growth of AI workloads. According to a report by Goldman Sachs, data center power demand is projected to increase by 165% by 2030, with AI-specific workloads accounting for over 27% of total power demand by 2027AI to drive 165% increase in data center power demand by 2030^[1].

onsemi's Strategic Play: Grid-to-Core Power Solutions

onsemi's acquisition of Vcore Power Technologies is a masterstroke in this context. By integrating Vcore's advanced power ICs—designed for high-density, low-loss power conversion—onsemi aims to address the entire power tree in AI data centers, from grid-level distribution to core-level chip power managementonsemi to Acquire Vcore Power Technology from Aura^[6]. This aligns with the company's vision to deliver scalable, practical designs that enhance compute capacity per rack while reducing energy waste.

Sudhir Gopalswamy, onsemi's group president, emphasized that the acquisition complements the company's existing expertise in silicon and SiC technologies, positioning it among the few firms capable of meeting the stringent power requirements of modern AI infrastructureonsemi Acquires Vcore Power Technologies to Enhance Power Management Portfolio for AI Data Centers^[7].

Competitive Landscape: onsemi's Differentiation in a Crowded Market

The power IC market is fiercely competitive, with players like Schneider Electric, Huawei, and Eaton investing heavily in GaN-based solutions and modular power architecturesData Center Power Market | Global Market Analysis^[9]. However, onsemi's acquisition of Vcore provides a unique edge: end-to-end power management tailored for AI's specific needs. While competitors focus on niche segments (e.g., DC distribution or cooling systems), onsemi's grid-to-core approach ensures seamless integration across layers, reducing complexity for data center operators.

Moreover, the acquisition aligns with broader industry trends. For example, 400V DC rack distribution is gaining traction for its efficiency advantages over traditional AC systems, and onsemi's SiC expertise positions it to capitalize on this shiftHow Next-Gen AI Data Centers Are Optimizing Power Efficiency with SiC^[10]. In contrast, rivals like Microchip and Infineon are still refining their SiC offerings, giving onsemi a first-mover advantage in AI-optimized power solutions.
